以白杨素为原料经磺化得白杨素-6-磺酸钠和白杨素-8-磺酸钠的混合物, 使其与ZnSO4反应生成相应的Zn衍生物. 利用Zn衍生物在热水中溶解度的差异, 分离得到纯的白杨素-6-磺酸衍生物及其8-位异构体. 6-位异构体经络合解聚得5,7-二羟黄酮-6-磺酸钠, 以此为配体与Al(III)作用得白杨素-6-磺酸铝配合物. 采用元素分析, IR, UV和1H NMR对化合物的结构进行了表征, 并对白杨素-6-磺酸铝配位化合物的荧光性能进行了探讨.

The mixture of sodium chrysin-6-sulfonate and chrysin-8-sulfonate was obtained by sulfonating chrysin and then reacted with ZnSO4 to get the corresponding Zn derivatives, which were separated according to the difference of their solubility in hot water. The pure Zn chrysin-6-sulfonate was transfered to the corresponding pure sodium sulfonate by the coordination and depolymerization procedures. Sodium 5,7-bihydroxyflavone-6-sulfonate (sodium chrysin-6-sulfonate) as a ligand reacted with Al(III) to afford a aluminium complex. All of new compounds were characterized by 1H NMR, IR, UV techniques and elemental analysis. And the fluorescence of the aluminium complex is explored as well.

Key words: chrysin, sulfation, coordination interaction, aluminium chrysin-6-sulfonate, fluorescence
